Adj Buckstrap Double Braid Steel Snaps. This relatively outdated lanyard style utilizes a friction-creating Prusik folded midline to provide the user with adjustment and full security at minimal cost. Designed originally for linesmen scaling telephone poles (which, of course, have minimal taper), the buckstrap required very little adjustment. Although used frequently by tree care workers, the buckstrap provides limited range on dramatically tapering trees. A secondary limitation of this lanyard is that the Prusik hitch (adjusting mechanism) will sometimes be located in a difficult-to-reach location on the opposite side of the tree because of the way the system is adjusted. If you like or are used to this type of lanyard, consider a Prusik-adjusting lanyard that keeps the Prusik on your hip!
